The Metaxas book is a collection of talks given at the "Socrates in the City" forum he organized in New York City. Each speaker's chapter includes the introduction Metaxas gave, the talk, and the questions and answers following. Chuck Colson and N.T. Wright are two of the names I could recognize right off the bat, as well as Metaxas himself whose biography of Bonhoeffer (Bonhoeffer: Pastor, Martyr, Prophet, Spy) I've read.

The other is a childhood favorite that I still like to revisit. I think of it when I go to Hi Hoe Nursery in the spring because they have a secluded area called a "secret garden."
